Lingua::EN::Numbers - turn "407" into "four hundred and seven", etc.
use Lingua::EN::Numbers qw(num2en num2en_ordinal); my $x = 234; my $y = 54; print "You have ", num2en($x), " things to do today!\n"; print "You will stop caring after the ", num2en_ordinal($y), ".\n";
You have two hundred and thirty-four things to do today! You will stop caring after the fifty-fourth.
This module provides a function
num2en, which converts a number (such as 123) into English text ("one hundred and twenty-three"). It also provides a function
num2en_ordinal, which converts a number into the ordinal form in words, so 54 becomes "fifty-fourth".
If you pass either function something that doesn't look like a number, they will return
This module can handle integers like "12" or "-3" and real numbers like "53.19".
This module also understands exponential notation -- it turns "4E9" into "four times ten to the ninth"). And it even turns "INF", "-INF", "NaN" into "infinity", "negative infinity", and "not a number", respectively.
Any commas in the input numbers are ignored.
The first version of this module, 0.01 released in May 1995, had an OO interface. This was finally dropped in the 1.08 release.
http://neilb.org/reviews/spell-numbers.html - a review of CPAN modules for converting numbers into English words.
The following modules will convert a number into words:
Lingua::EN::Inflect provides a lot more besides, including conversion of singular to plural, selecting whether to use 'an' or 'a' before a word, and plenty more
Lingua::EN::Nums2Words provides similar functionality, but can't handle exponential notation, and 3.14 produces "three and fourteen hundredths" instead of "three point one four".
Math::BigInt::Named doesn't work.
Number::Spell doesn't handle negative numbers, exponential notation, or non-integer real numbers. The generated text doesn't contain any commas or the word 'and', so the results for long numbers don't scan.
There are other modules which provide related, but not identical, functionality:
Lingua::EN::Numbers::Ordinate provides a function that will convert a cardinal number (such as "3") to an ordinal ("3rd").
Lingua::EN::Numbers::Years provides a function that will convert a year in numerals (eg "1984") into words ("nineteen eighty-four").
Lingua::EN::Fractions provides a function that will convert a numeric fraction (eg "3/4") into words ("three quarters").

The first release to CPAN, 0.01, was written by Stephen Pandich in 1999.
Sean M Burke took over maintenance in 2005, and completely rewrote the module, releasing versions 0.02 and 1.01.
Neil Bowers <email@example.com> has been maintaining the module since 2011.
